ADJUSTABLE RAIL FITTING.

Application led May 29', 1920. Y Serial No. 385,321.

To all whom t may ccf/wem:

Be it known that I, SELDEN J. GULEsrAN, a citizen of the United States, residing at Revere, in the countyof Suffolk and State of Massachusetts, have invented new vand useful Improvements in Adjustable Rail Fittings, of which the following is a specication.

M invention relates to rail iittings, and its object is to provide improved adjustable means for connecting pipe rails to form stairway balustrades and the like.

In Letters Patent of the United States No. 1,304,561 issued to me under date May 27, 1919, are disclosed means for varying the angles between the upright or supporting member and the intermediate rails in a vertical plane; in the present invention further adjustability is obtained through means adapted to eect variation of the angles between the intermediate rails in horizontal and inclined planes.

My new and improved connection consists essentially of a stanchion or other supporting member provided with a hollow spherical cap comprising a plurality of independent elements, each of said elements being provided with suitable means for receiving` and retaining the end of a pipe rail. These cap elements are secured at the point of union, which lies in a horizontal plane, by shoulder joints upon which the elements are rotated relatively to each other, thus varying the angles between the vertical planes in which the intermediate rails secured to said elements respectively lie.

My invention further resides in the particular form and combination of parts hereinafter more Jfully described and claimed and shown in the drawing accompanying this specification in which like numerals of reference indicate corresponding parts in the various figures thereof, and in which Fig. 1 is an elevation of one type of my new and improved device, Fig. 1a is a vertical section of the same, and Figs. 2, 3, and 4 are vertical sections of other types of ttings embodying my invention.

Referring to Fig. 1a, in which is shown the type of fitting adapted to the combination of horizontal and upwardly inclined rail, 5 is a stanchion or upright support, provided with the spherical cap 6 composed of the members 7 and 8. The screw threaded extremity 12 of the bolt 9, the head 10 of which is countersunk in theaperture 11 in the member 8, passes through the aperture 13 in the stanchion 5 and is engaged `by the nut 14, thus securing in the desired relation the stanchion 5, and members 7 and 8. 15 is an interiorly screw threaded collar adapted tofreceive and retain a horizontally dis posed intermediate rail. Abolt 16 is passed through the central aperture 17 in the cross piece 184 of the collar 15, and the screw threaded extremity 19 of the bolt 16 engages a screw threaded aperture 20 inthe wall of the-member 7, thus securing in operative relation the horizontal rail collar 15 and the stanchion 5. A collar 21 of the type of the collar 15 and adapted to receive and retain an inclined intermediate rail is secured to engages a slot 23 in the member 8 and the aperture 24 in the cross piece 25 in the collar 21. A nut 26 enga es the screw threaded extremity 27 of the olt 22 and secures the member 8 and inclined rail collar 21 in the required relation. The slot 23 is disposed to permit a limited movement of the bolt 22 in a vertical plane, and thus effect variation in vertical p ane angle between the horizontal and inclined rails, while variation in the angle between the vertical planes in which the horizontal and inclined rails respectively lie is effected by rotation of the member 8 relatively to the member 7.

In Fig. 2 is shown the type of fitting adapted to the combination of horizontal with downwardly inclined rail. In this type the horizontal rail collar 15 is mounted upon the upper member 82L of the cap 6a which in this type is separated into the members 7a and 8a below its center instead of above as in Fig. 1a, and the collar 21at is mounted upon the lower member 7a and is sheared at 28 to permit its periphery to embrace the stanchion 5, thus providing greater latitude in the range of angles between the stanchion and the inclined rail. As in the type shown in Fig. la variation of the angle between the vertical planes in which the horizontal and inclined rails respectively lie is eii'ected by rotation of the member 8a relatively to the member 7a.

In Fig. 3 is shown the type of itting type of fitting embodying my invention which enables the advantages thereof to be obtained in commercial practice with fewer stock parts. In this type the spherical cap comprises three instead oit' two independent members, the lower member 7b, upper member 8b and the intermediate ring 29, which serve to perform all the functions of the cap members 7, 8, 7a and 8a. In the ordinary and most common use, only two of the collars l5, 2l, and 21- would be employed in combination with a single cap, 15 and 21 for the combination of horizontal and upwardly inclined rails, 15 and 21a for the combination of horizontal and downwardly inclined rails, and 2l and 2l for the combination of upwardly and downwardly inclined rails, but exceptional situations arise where it is useful and convenient to employ a combination in which all three collars similar to 15, 2l and 21a, would be used in a single cap and attached to three independent elements respectively.

TWhat I claim and desire to secure by Letters Patent is: v

An adjustable pipe rail tting, comprising in combination a stanchion, a hollow spherical stanchion cap composed of three members, capable of adjustment horizontally and independently of each other, a pipe rail secured to each member, means for vertically adjusting the rail connected to each of the upper and lower members and means for securing said rails in Various angles relatively to each other.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses, this fourteenth day of May, 1920.

SELDEN JOHN GULESIAN.
